Changes in version 0.3-5
	-bug fixes:
		-getExpectedSize failed in rare cases
Changes in version 0.3-4
	-added summary method for RLResult objects
	-bug fixes:
		-summary.RecLinkResult failed for object without known
		 matching status
Changes in version 0.3-3
	-added new classification method "bumping", see ?trainSupv
	-bug fixes:
		- string comparators crashed for character(0) input
		  (reported by Dominik Reusser)
		- getPairs could fail when the result is emtpy
	-various performance improvements
	-renamed vignette "Fellegi-Sunter Deduplication" to 
	 "Weight-based deduplication"
	-package is now in a namespace

Changes in version 0.3-2
	- performance improvements in various functions
	- bug fixes:
		- epiClassify failed for datasets with only one column
		  (reported by Richard Herron)
		- getErrorMeasures returned wrong values in rare cases

Changes in version 0.3-1
	- fixed bug in emClassify that threw an error during  classification 
	  with on-the-fly calculation of weights
	- added checks in unit tests
	- fixed bug in optimalThreshold which caused wrong results in some
	  cases when ny was supplied
	- added status messages and progress bars to various classification functions
	- fixed numerical problem that produced wrong thresholds in some cases
    for emClassify (with my / ny supplied) 

Changes in version 0.3-0

	- A framework of S4 methods and classes tailored for processing large
	  data sets has been added. See the vignette 'BigData' for details.
  	- The output format of getPairs (existing method for RecLinkData and
	  RecLinkResult objects) has changed: Column "Weight" is now last instead
	  of first. Also, for single.rows=FALSE, record pairs are speparated by
	  a blank line.

Changes in version 0.2-6

	- added subset operator [ for RecLinkData and RecLinkPairs objects
	- improved running time of epiWeights significantly

Changes in version 0.2-5

	- Fixed a bug in getMinimalTrain which caused the function to fail

Changes in version 0.2-4

	- Fixed a bug in getMinimalTrain that caused pairs with unknown
		matching status to become non-matches in the training set.
	- Some examples were modified to reduce execution time.
	- Unit tests have been added in inst/unitTests.
	- Checking of arguments improved in some functions.
	- Small documentation changes.
Changes in version 0.2-3

  - getParetoThreshold now prompts a message if no data lies in the
    interactively selected interval and asks the user to choose again
  - Corrected maintainer e-mail address
  - Several bug fixes
